Our greeting cards are printed using 300 gsm white linen recyclable card. They come custom made to order, including envelopes. We match our coloured envelopes best to the card you pick! Envelopes come in Blue, Pink, Orange, Yellow, Green & White. If you want to specify a colour, please write in the notes of your order! Choose either A6 (10.5cm/14.8cm) or A5 (14.8cm/21cm). Please allow 3-5 working days for delivery as each card is custom made with care in our UK studio, for you after order.
